Hi @bao2007happy
You need to provide much more information.
Which OS are you using - and are you running the lein command in a directory with a very long path?
Try running these commands and provide the output:

java -version
nodejs --version
lein --version
yarn --version
lsb_release -d
git log -1 --format="commit %H"
git status | head -1

hello,My OS is windows.
My running environment meets the requirements of metabase.
JDK v1.8.0_171
nodejs v12.11.1
lein v2.9.1
yarn v1.19.0
Git is not associated with the current project
It seems to be a Windows problem. I don’t know if there is a solution

@bao2007happy
Well, there has been a known limitation of path in Windows since forever - think the limit of the entire length of a path is 256 characters. I don’t think it was been fixed and will likely not be fixed until they change file system, since I think it’s a limitation of NTFS.

yeah,By modifying the windows file path limit, it has been solved,thank you!

I have tried to change the path of the Metabase source folder still getting the same error.
What path do we need to change in order to fix the issue?

@jeevang You would probably need to try WSL2 or a different OS if you’re hitting limitations in Windows.

Longpath files are too problematic. I searched a lot and finally found this tool known as Longpath tool. It helps alot.

I agree John. I have been using it and it is quite helpful.

Yes, I too agree. Longpath tool has solved many problems of longpath files.
